Everyone spent all of Season 3’s build up wondering how Ian Bohen would fit into Taylor Sheridan’s CIA thriller, and the premiere finally gave an answer that hit harder than expected.
Bohen, best known as Ryan across all five seasons of Yellowstone, was officially cast in the role back in October 2025, right as Season 3 production kicked off in Texas. For Bohen, landing on Lioness wasn’t a new pursuit. He had tried to join the show as early as Season 2, but scheduling conflicts got in the way after he was promoted to a series regular on Yellowstone for its final two seasons.
Grady Is the Delta Force K9 Handler in Lioness Season 3
Grady is described as a by-the-book Delta Force operator and primary K9 handler, skilled in battlefield tactics. Rather than folding him into Joe McNamara’s undercover Lioness team, Sheridan uses Grady to widen the show’s lens beyond infiltration missions and into the broader special operations world backing them up.
That shift is deliberate. Seasons 1 and 2 largely centered on Joe recruiting and training a single undercover operator for one target. Season 3 pulls the camera back, and Grady’s presence as a battlefield-facing operator is a big part of how the show builds out that larger ensemble around Zoe Saldaña’s Joe.
Grady makes his debut in the Season 3 during a mission in Ukraine, working alongside his dog Titan. Bohen described the assignment as unexpectedly emotional to shoot, since so much of Grady’s introduction hinges on his bond with the dog rather than dialogue heavy exposition.

Titan’s Death and the Fallout for Grady
Here’s where Grady’s story takes a gut punch. During the Ukraine operation, Titan is stabbed while helping neutralize enemy soldiers in the trenches, and the injury proves fatal. Grady is left visibly despondent, and the moment lands as one of the premiere’s most talked about beats.
Bohen has been candid about how personal the storyline felt. He told TV Insider that finding out his character’s dog wouldn’t survive was devastating for him as an actor, on top of the emotional weight Grady carries in the scene itself. He also mentioned getting hate mail from his own family over how the moment played out, a sign of just how attached viewers and even his loved ones got to Titan in a single episode.
It’s a bold way to introduce a new series regular, using loss instead of a big action set piece to define him. But it works, because it immediately tells the audience who Grady is: a soldier who treats his K9 partner as family, not equipment.
With Grady now folded into the wider Lioness orbit, expect his skill set and his grief over Titan to keep shaping the season’s special ops storylines as the missions escalate.
Lioness Season 3 airs Sundays on Paramount+.
